In order to activate the telecoil, the telecoil program available in program 3 must be
selected.
Cellular Phone and Hearing Instrument Compatibility
Hearing instrument performance with cellular phones may vary based on the individual
hearing system or the cell phone being used. If your hearing system and cell phone are
not compatible you may experience a buzzing or clicking noise while using the two in
conjunction. If this is the case with your current hearing system and cell phone, consult
with your hearing healthcare professional to see if there are options to improve the sound
quality.
Measures you can take to prevent this situation:
•When purchasing a hearing system, be sure to test it with your existing phone to
determine compatibility.
•When shopping for a new cell phone, be sure to test it with your hearing system
before purchasing.
For additional guidance, please consult your cell phone provider.
Telephone use
Using the telephone, while wearing your hearing instrument, may
require some practice. Many hearing instruments will whistle,
when the phone is held up against them. To avoid this problem,
your hearing instrument has an induction coil. By switching the
program button to the telecoil program (typically program 3), the
hearing instrument will only pick up sounds coming from the te-
lephone. You may need to adjust the volume on the hearing in-
strument to improve hearing understanding on the telephone.
The receiver of the telephone should be placed as shown in the
drawing.
Telecoil-Program
Your hearing instrument has a built in function called the telecoil, which offers improved
hearing when used with a telecoil compatible telephone or assistive listening device.
In this program, you typically will not be able to hear any sound from the microphone,
but will be able to get direct sound input via a telecoil compatible telephone and/or a loop
system, e.g. in churches, theatres, etc., or at home.
